SHOBTEK CONTRIBUTIONS TO GENERAL GEOLOGY, 1921. 



Island to Maryland, in tho Black Creek forma- 

 tion of North Carolina, in the Middendorf 

 arkose member of the Black Ci-eek formation 

 of South Carolina, in the Binr^en sand of Arkan- 

 sas, in the Tuscaloosa formation of Georgia 

 and Alabama, in the Eutaw formation of Geor- 

 gia, in the Ripley formation of Tennessee, and 

 in the Dakota sandstone of Kansas. It ap- 

 pears to be present in the Upper Cretaceous of 

 the Pacific coast on Vancouver Island and to 

 be represented in Texas by the remains of Cin- 

 ■namomum ri'corded by Knowlton " from the 

 Woodbine sand in Cooke County. Although 

 not kiiown from Europe, the forms from the 

 Cenomanian of Bohemia which Velenovsky ^* 

 described as Aralia da-phnophyUnm are very 

 similar to the American species. 



The specimens found in the Dakota sand- 

 stone came from Ellsworth County, Kans., and 

 the range elsewhere of this species seems to 

 prov<> that the formation was the true Dakota 

 sandstone rather than some older sandstone. 



It seems obvious that the range of this form 

 represents more than a single botanic species, 

 as no question of correlation is involved in the 

 eastern Gulf section from Tuscaloosa to Ripley, 

 but the only criteria for segregation are strati- 

 graphic. The leaves of Cutiiatnomum, both 

 living ami fossil, are notoriously variable, so 

 that the problem appears insoluble. 



The species is not abundant in the Woodbine 

 material from Arthurs Bluff, Tex., but I regard 

 this scarcity as merely an accident of preserva- 

 tion or discovery.

This species, which Lesquereux referred to 

 the genus Palinnix, was described originally 

 from specimens collected at Decatur, Nebr., 

 and Pipe Creek, Kans. It occurs in the north- 

 ward e.xtension of the Magothy formation at 

 Gay Head, Marthas Mneyard, Mass., and in the 

 Woodbine sand at Arthurs Blufl', Tex. I

think that Hollick was entirely justified in 

 removing this form from Paliurus, but I am 

 not sure that it is a Cinnamomum, although it 

 appears to be a lauraceous form. If a Cinna- 

 momum, as is perfectly possible, it should 

 probably be regarded as a variant of the con- 

 temporaneous Cinnnmomum newherryi, from 

 which it differs merely in its irregularity of 

 outline.

Leaves lanceolate, usually tapering almost 

 equally in both directions but some specimens 

 less "acute at the base. Length, 7 to 11 centi- 

 meters: greatest width, 1.5 to 2.5 centuneters. 

 Midrib fairly stout. Petiole short and stout, 

 6 to 15 millimeters in length. Secondaries 

 slender, eight or more alternate pairs, camp- 

 todrome. 



This species was described by Heer from 

 material collected in the Atane beds of western 

 Greenland, and a large number of somewhat 

 variaV)le and fragmentary specimens were 

 figured. vSubse(|uently it was I'eeorded from 

 a very large number of Cretaceous plant beds, 

 so that its range both geographic and geologic 

 is rather extensive. A number oi these records 

 are not entirely above suspicion, and this
